FMV Stutter crash –
I've been trying to get FFXII NTSC working perfectly on my PS3 all this morning.
I was having issues with the FMV stuttering and then eventually the whole game would crash leaving me with glitched audio.
I've managed have one instance of the game NOT crashing, although it isn't repeatable. Here are my notes.
My setup originally consisted of my PS3 connected to the router via 100mb eth and then wirelessly over 802.11n (216mbps) to my desktop where the iso's were shared.
Watching task manager, throughput was always below 5%, it did not appear that watching FMV's stressed bandwidth at all and considering I routinely watch divx through WMP DLNA server I found the stuttering to be odd.
Using my laptop I pinged the PS3 whilst it was trying to play the intro FMV, the first few pings were 10 ms or less but then it jumped to over 3000 ms each and lots of lost packets.
Not getting anywhere I created a new wired network with another router between the PS3 and PC, so it was 100mb eth the whole way.
Playback improved dramatically, although it wasn't perfect. The intro FMV played completely but the FMV you watch after starting the game had a few stutter points and eventually crashed.
Using all this evidence the only thing I can think is that the PS3 is streaming tiny little bits of the FMV at a time, which explains why the bandwidth usage is so low. However it appears PS2 is very sensitive to latency, its like the stutters cause the game to become out of sync somehow upsetting what appears to be only a few threads of execution and then crashing.
Using this knowledge I tried to think of ways to reduce latency between the PS3 and PC. I didn't have a crossover cable so I couldn't do a direct end to end.
I ended up moving the share from a 1TB hard drive with 5400rpm speed on a SATA1 SIL3114 controller to a 500GB 7200rpm drive on the nforce 4 SATA2.
This is the best I have managed to get it. The first couple of times it would still crash, but on the 3rd try it went fine, getting through the almost 8 min FMV.
I tried moving the share to a windows 7 mirrored drive (2x 500GB drives mirrored using software). Performance was terrible. After 5 sec of playback the intro movie would crash immediately.
Anyone got any notes on improving performance?
if the fmv in the game isnt too important, u could try removing it/replacing it with dummy files, or if u want to keep the movie files, use special software to reduce the bitrate of the fmv files. obviously to do all this u would need to understand how to rebuild a game/iso image though. it's a pain to do, but it's possible (i had to do it myself for a few games which crash, due to 'too intense' movie (fmv) files .. like you have with the final fantasy fmv's.....)
ps. if u could run the game on eg. usb hd instead of network, you would have the option to use PS2ESDL.. which has excellent handling of fmv files, and various options* to avoid crashes when using 'troublesome' fmv files such as the ones you mention.
* eg. force syncronization mode.. cache size options, etc
